Fraggle, you're from Bohemia? (Which is the the Czech Republic, right?) My family (part of it) comes from the former Czechoslovakia area.
The Romans named an area (which comprises the majority of the modern Czech Republic) Bohemia, because at that time a Celtic tribe, the Bohumil, lived there. The Slavs had not arrived in central Europe yet. The Balts and Slavs were the last of the Indo-European tribes to show up in Europe. Unlike the Western Indo-European tribes (the Celtic, Germanic, Hellenic, Italic and Albanian peoples), who came straight up from the ancestral homeland in the Anatolia-Georgia region, the Balts and Slavs are an Eastern Indo-European tribe more closely related to the Indic, Persian, Kurdish and Armenian peoples, and they came up the long way, after first stopping off in India.
The ancestors of the Czechs and Slovaks (presumably a single tribe at that time since their modern languages could be considered merely dialects of the same tongue) found their way into Bohemia and evicted the Bohumil around 300-400CE. By then the name Bohemia was established and it was used by all the western and southern Europeans clear up into the 20th century, e.g. German
Böhmen. It didn't help that the Czechs named the place
Čechy, after themselves, and no one else could spell or pronounce it.
When the Czechs and Slovaks united their countries after WWI, it was natural to call it
Československo, running the two names together with proper grammatical inflections. The rest of the continent used the Polish form of that name,
Czechoslovakia, presumably because it doesn't require the use of diacritical marks.
When the two countries split up again after Perestroika, the Slovaks retrieved their original name for their country,
Slovensko, and we call it Slovakia using the Latin model for country names. However, the Czechs could not call their half by the original name
Čechy, because that name only describes the homeland of the Czechs, Bohemia itself, whereas the country also encompasses Moravia--a region with its own history which we'll leave for another time. So they call it
Česka Republika, "the Czech Republic."
My mother's parents emigrated from Bohemia about 120 years ago, after first trying a couple of other places including Yugoslavia and Australia. She was born in Chicago, grew up speaking Czech until she went to school, but never visited the old country. I was also born in Chicago but I celebrated my 30th birthday in Praha.
they wanted to be all things American. My grandmother even changed her name to something more American.
What could be more American than a northwestern European surname??? The English, Scots, Dutch and French founded this country! Today Irish (Kennedy) and German (Bush) surnames are also regarded as completely American.
